This is probably my favorite of the jam games. I played the jam version and even with some of the jank had a ton of fun.
The genre is a dungeon-crawling RPG, but there are no levels so the only "grinding" is in getting upgrades to equipment, new abilities, and MP boosts. Overall the gameplay was good, although a lot of skills I didn't have a good use for.
The concept is hilarious and I love the constant jokes throughout the game.
The visuals were very good, I loved the pixel art and character portraits. The mouths moving during dialogue were a polished touch I wouldn't expect from a game jam. The enemy sprites were also great. I think my favorite was the Fiery.
The music was great, but it did get kind of repetitive due to how much you hear the battle music. That's a problem I had with a lot of RPGs. I recommend turning the music off when grinding and listening to something else, and turning it back on when you go to make progress.
The writing was very good, and overall had a comedic tone that managed to almost make me laugh (it's very rare for me to laugh at something that's intended to be funny) at points.
The weakest point of the game was the challenge. Most bosses were impossible until I got the upgrades for the floors I was on, then they became trivial. The strategy I settled on for most bosses was to inflict the blind status with Extending Arm, then use the dodge moves to reduce my chance to get hit. If you grind some of the secret enemies (hint: check the fishing spots), you can get equipment that completely destroys the game. This is a point in favor of the game, I totally love RPGs with broken items. It did get a tad bit repetitive to farm upgrade items, though.
The relationship of Hina and Nitori was handled in a way I liked. It also was incorporated into the game mechanics, as they become stronger as their love for each other grows. I kind of wish there was something that showed them being close at the end, but I guess the ending fits with the comedic tone of the game.
Overall, this would definitely be my favorite of the games with a bit more polish.
